Abstract: 1,182,163. Sheet folding apparatus. G. MATTKA. 30 June, 1967 [1 July, 1966], No. 30387/67. Heading B8R. A sheet-folding machine comprises at least one blade-folding unit having a sheet stop engaging the leading edge of a sheet and locating it relative to the folding blade and a feed device which simultaneously aligns a sheet being fed to the blade-folding unit against the sheet stop and against a longitudinal guide for the edge of the sheet. Fig. 28 is a side elevation of a blade-folding unit which can be capable of optional combination with other folding mechanisms on the machine at various heights either parallel to or in angular displacement relative to, these other mechanisms; a sheet to be processed arrives at a feeding device 11 and is conveyed by obliquelyarranged rollers 12 to a blade-folding unit 14. A guide 13 (also Figs. 29, 30, not shown) aligns the feed direction to be perpendicular to the displacement plane of folding blade 16; the sheet passes over two folding rollers 15 and is supported by plates 17 until the leading edge strikes a sheet stop 18; conveying of the sheet may be aided by belt 19 on rollers 20, 21. On actuation of blade 16, the folded sheet passes through the nip of rollers 15 and is guided by rockable sheet guide 22 towards outlets a or i of mechanism 14; removal of the sheet may be aided by a further conveyer belt 24 on rollers 23. Two cutter shafts may be located between the folding rollers 15 and the sheet guide 22 (Fig. 31, not shown); the two folding rollers may also be followed by a further roller and pocket to produce a buckling-folder (Fig. 32, not shown).

Title: Improvements in methods of and apparatus for determining the moisture content of powdery and granular material
IPC: G01N9/36
Filed: 1934-10-26
Abstract: 444,077. Weighing-apparatus. JAEGER TRUCK MIXERS (ENGLAND), Ltd., 54, Victoria Street, Westminster, and BELL, R. T., 43, Belsize Avenue, Hampstead, London. Oct. 26, 1934, No. 30708. [Class 143] [See also Group XX] The moisture-content of solid material, e.g. sand or gravel for making concrete, is determined by placing in a test vessel in the scale pan of a weighing scale of the moving pointer type a quantity of the moist material sufficient to bring the pointer to an index mark, the position of which is predetermined in accordance with the specific gravity of the material when dry, and thereafter adding water to bring the mixture of material and water to a predetermined volume (e.g. the whole volume of the test vessel), the moisture content being then indicated by the pointer on a, moisture content scale. In the weighing scale shown, the single index mark is replaced by a number of specific gravity graduations 12 for use with materials of different specific gravity. The moisture content scale 14 decreases in a direction away from the zero of the pointer 2. The weighing scale may be provided with an index mark A and a specific gravity scale 10 for use in determining the specific gravity of the material when dry. In use sufficient dry material is placed in the test vessel 6 to bring the pointer 2 to the index A. The vessel 6 is then filled with water, the pivoted lid 16 swung to the closed position, and the specific gravity read off from the position to which the pointer moves on the scale 10. The vessel 6 is then emptied and a quantity of the moist material sufficient to move the pointer 2 to the specific gravity graduation on the scale 12 corresponding to that determined from the scale 10 is placed in the vessel 6. The latter is then filled with water and the moisture content is indicated directly on the scale 14.

[Class 65 (i).] A spring closing and fluid check device for doors is provided with a pair of springs acting cumulatively to rotate the driving shaft in the closing direction but extending in diametrically opposite directions relatively to the shaft so that their thrusts against the shaft balance. The form shown is designed to be concealed in the top of a door, the main shaft 14 being operated by an arm 15 fixed on it and connected by a link to the door frame ; the device is shown in the open position of the door, the door hinge being adjacent on the right, and the arrangement is such that the arm 15 moves through approximately 180‹ relative to the door, in a clockwise direction in plan, during the closing movement. The shaft 14 carries a pinion 28 engaging with a rack 29, having an abutment for the left-hand spring 31, and a similar rack (not shown) in front engaging the right-hand spring. The lower part of the shaft 14 carries another pinion 37 engaging with a rack 38 attached to a check cylinder 41 sliding over a fixed piston 42, the whole lower part of the casing of the apparatus forming an oil reservoir. The piston has an axial passage connecting the exterior with the interior of the cylinder through a ball valve 47 for the admission of oil, and escape of oil during closing takes place through two check valves (not shown), having stems 51 for adjustment, the exhaust port of one of the valves being covered before the closing movement is completed.

Abstract: 1,208,549. Electrode processing. THOMSONCSF. 19 June, 1969 [2 July, 1968], No. 31193/69. Heading H1D. [Also in Division C7] In making a channel multiplier of the type wherein a resistive secondary emissive layer is deposited on the interior surface of a glass tube, the tube is cut in halves longitudinally before the layer is deposited so that the quality of the deposit may be improved. The layer may be of tin oxide and may be evaporated or sputtered on to the tube halves in a vacuum chamber; the layer may be deposited at the same time on a crystal to monitor the thickness of the deposit or on to a glass plate provided with electrodes through which the resistivity of the deposit may be monitored. The tube may be straight or circular. In one example the tube is circular and has an overall length of 75 mm. and a diameter of 1 mm, and the coating is 2000  thick. The two halves of the tube are clamped together at the two ends by crimped collars, and at the centre by an adhesive-bonded collar.

Abstract: 795,602. Thermionic valves. GENERAL ELECTRIC CO. Oct. 12, 1956 [Oct. 14, 1955], No. 31194/56. Class 39(1). In an electron tube, grids 15 and 16, Fig. 1, are supported by rods 17 and 18, the ends of which pass through mica spacer plates 21 and 22. The rods are held in rigid engagement with these plates by means of straps 23 affixed to the rods adjacent the plates and deformed during assembly so that they are firmly wedged against the plates. The straps, before deformation, are U-shaped or J-shaped, Fig. 4a, one end 25 being spot-welded to the support rod 17. The other end 24 is then bent round to form a bight and is welded to the fixed end, Fig. 4b. Finally the bight is flattened against the rod 17, Fig. 4c. Alternatively an arcuate shaped member 31, Fig. 7, may be welded at its upper end to the rod 17 and afterwards straightened out, Fig. 8, thereby deforming the mica plate 21 and ensuring tight clamping. With a strap at each end, the rods, and therefore the grids, are fixed relative to the mica plates. Other electrodes, such as anodes and cathodes, having portions which extend through a transverse supporting plate may be fixed in this way.
